This keto mug bread is low in carbs, sugar and calories, but high in protein and fibre – perfect for satisfying your cravings without kicking you out of ketosis. 

Flaxseed is a great addition to any diet but particularly a keto diet as they’re a source of protein, fibre and omega-3 fatty acids. They’re one of the world’s oldest cultivated crops and come in brown and golden forms which both have a mild, savoury flavour which lends itself perfectly to bread recipes. They provide a whole host of health benefits including supporting heart health, protecting against cancers like breast cancer and blood cancer, and even assisting in weight loss.

Similarly, ground almonds are a wonderful ingredient to keep stocked up on for recipes like this keto mug bread. They’re rich in nutrients like calcium, fibre and vitamin E which support bone, brain and gut health. What’s more is that they’re high in magnesium, which many of us don’t get enough of, which plays a role in controlling blood sugar levels. So, while traditional bread usually spikes your blood sugars, this keto mug bread can actually help to control your blood sugar!

This recipe serves two, so make sure to whip up a batch to either share or freeze half for another day. For homemade bread that’s keto friendly and takes just a couple of minutes to throw together, this really is a recipe to give a go.

Nutrition facts(per serving)


  • 12g salted butter
  • 15g flaxseed
  • 35g ground almonds
  • 10g pumpkin seeds 
  • 1 tsp baking powder
  • 1 small free-range egg


  1. Melt the butter in a large mug in the microwave for about 10-15 seconds. Swirl it around to grease the sides.
  2. Mix all remaining ingredients in the mug with a fork until well combined. 
  3. Microwave on high for 60–90 seconds (this may differ depending on your microwave wattage). 
  4. Tap the top, if it’s firm and springy it’s ready. Return to the microwave for 10 seconds at a time if it is still soft to touch.
  5. Turn the bread out (give it a tap if needed) and cool on a wire rack before cutting into slices to serve.


  • You may find a few holes in the bread when you turn it out of the mug. 
  • It is best eaten on the same day, but you can also slice and freeze extra portions for toast.
  • This recipe is intended as a side dish, while it’s low carb it may be better to consume on non-fasting days due to the calories. Serve this bread as toast alongside eggs, or top with tomato, avocado and salad. The options are up to you!
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat and serve.
  • If following a gluten free diet, please check the label of the baking powder to ensure there are no sources of gluten.
